-Barometer Configuration
-========================
-This document provides guidelines on how to install and configure the Barometer
-plugin when using Fuel as a deployment tool. The plugin name is: Collectd
-Ceilometer Plugin. This plugin installs collectd on a compute node and enables
-a number of collectd plugins to collect metrics and events from the platform
-and send them to ceilometer.

+Barometer Configuration Guide
+=============================
+This document provides guidelines on how to install and configure Barometer with Apex.
+The deployment script installs and enables a series of collectd plugins on the compute node(s),
+which collect and dispatch specific metrics and events from the platform.

Pre-configuration activities
----------------------------
-The Barometer Fuel plugin can be found in /opt/opnfv on the fuel master.
-To enable this plugin:
+Deploying the Barometer components in Apex is done through the deploy-opnfv command by selecting
+a scenario-file which contains the ``barometer: true`` option. These files are located on the
+Jump Host in the ``/etc/opnfv-apex/ folder``. Two scenarios are pre-defined to include Barometer,
+and they are: ``os-nosdn-bar-ha.yaml`` and ``os-nosdn-bar-noha.yaml``.
.. code:: bash
- $ cd /opt/opnfv
- $ fuel plugins --install fuel-plugin-collectd-ceilometer-1.0-1.0.0-1.noarch.rpm
-
-On the Fuel UI, create a new environment.
-* In Settings > OpenStack Services
-* Enable "Install Ceilometer and Aodh"
-* In Settings > Other
-* Enable "Deploy Collectd Ceilometer Plugin"
-* Enable the barometer plugins you'd like to deploy using the checkboxes
-* Continue with environment configuration and deployment as normal.
+ $ cd /etc/opnfv-apex
+ $ opnfv-deploy -d os-nosdn-bar-ha.yaml -n network_settings.yaml -i inventory.yaml –- debug
Hardware configuration
----------------------
-There's no specific Hardware configuration required for this the barometer fuel plugin.
+There's no specific Hardware configuration required. However, the ``intel_rdt`` plugin works
+only on platforms with Intel CPUs.
Feature configuration
---------------------
-Describe the procedures to configure your feature on the platform in order
-that it is ready to use according to the feature instructions in the platform
-user guide. Where applicable you should add content in the postinstall.rst
-to validate the feature is configured for use.
-(checking components are installed correctly etc...)
-
-Upgrading the plugin
---------------------
-
-From time to time new versions of the plugin may become available.
-
-The plugin cannot be upgraded if an active environment is using the plugin.
-
-In order to upgrade the plugin:
-
-* Copy the updated plugin file to the fuel-master.
-* On the Fuel UI, reset the environment.
-* On the Fuel CLI "fuel plugins --update <fuel-plugin-file>"
-* On the Fuel UI, re-deploy the environment.
+All Barometer plugins are automatically deployed on all compute nodes. There is no option to
+selectively install only a subset of plugins. Any custom disabling or configuration must be done
+directly on the compute node(s) after the deployment is completed.
+Upgrading the plugins
+---------------------
+The Barometer components are built-in in the Apex ISO image, and respectively the Apex RPMs. There
+is no simple way to update only the Barometer plugins in an existing deployment.

Barometer post installation procedures
======================================
-Add a brief introduction to the methods of validating the installation
-according to this specific installer or feature.
+This document describes briefly the methods of validating the Barometer installation.
Automated post installation activities
--------------------------------------
-Describe specific post installation activities performed by the OPNFV
-deployment pipeline including testing activities and reports. Refer to
-the relevant testing guides, results, and release notes.
-
-note: this section should be singular and derived from the test projects
-once we have one test suite to run for all deploy tools. This is not the
-case yet so each deploy tool will need to provide (hopefully very simillar)
-documentation of this.
+The Barometer test-suite in Functest is called ``barometercollectd`` and is part of the ``Features``
+tier. Running these tests is done automatically by the OPNFV deployment pipeline on the supported
+scenarios. The testing consists of basic verifications that each plugin is functional per their
+default configurations. Inside the Functest container, the detailed results can be found in the
+``/home/opnfv/functest/results/barometercollectd.log``.
Barometer post configuration procedures
---------------------------------------
-The fuel plugin installs collectd and its plugins on compute nodes.
-separate config files for each of the collectd plugins. These
-configuration files can be found on the compute node @
-`/etc/collectd/collectd.conf.d/` directory. Each collectd plugin will
-have its own configuration file with a default configuration for each
-plugin. You can override any of the plugin configurations, by modifying
-the configuration file and restarting the collectd service on the compute node.
+---------------------------------------
+The functionality for each plugin (such as enabling/disabling and configuring its capabilities)
+is controlled as described in the User Guide through their individual ``.conf`` file located in
+the ``/etc/collectd/collectd.conf.d/`` folder on the compute node(s). In order for any changes to
+take effect, the collectd service must be stopped and then started again.
Platform components validation
----------------------------------
-1. SSH to a compute node and ensure that the collectd service is running.
+------------------------------
+The following steps describe how to perform a simple "manual" testing of the Barometer components:
+
+1. Connect to any compute node and ensure that the collectd service is running. The log file
+ ``collectd.log`` should contain no errors and should indicate that each plugin was successfully
+ loaded. For example, from the Jump Host:
+
+ .. code:: bash
+
+ $ opnfv-util overcloud compute0
+ $ ls /etc/collectd/collectd.conf.d/
+ $ systemctl status collectd
+ $ vi /opt/stack/collectd.log
-2. On the compute node, you need to inject a corrected memory error:
+ The following plugings should be found loaded:
+ aodh, gnocchi, hugepages, intel_rdt, mcelog, ovs_events, ovs_stats, snmp, virt
-.. code:: bash
+2. On the compute node, induce an event monitored by the plugins; e.g. a corrected memory error:
- $ git clone https://git.kernel.org/pub/scm/utils/cpu/mce/mce-inject.git
- $ cd mce-inject
- $ make
- $ modprobe mce-inject
+ .. code:: bash
-Modify the test/corrected script to include the following:
+ $ git clone https://git.kernel.org/pub/scm/utils/cpu/mce/mce-inject.git
+ $ cd mce-inject
+ $ make
+ $ modprobe mce-inject
-.. code:: bash
+ Modify the test/corrected script to include the following:
- CPU 0 BANK 0
- STATUS 0xcc00008000010090
- ADDR 0x0010FFFFFFF
+ .. code:: bash
-Inject the error:
+ CPU 0 BANK 0
+ STATUS 0xcc00008000010090
+ ADDR 0x0010FFFFFFF
-.. code:: bash
+ Inject the error:
- $ ./mce-inject < test/corrected
+ .. code:: bash
-3. SSH to openstack controller node and query the ceilometer DB:
+ $ ./mce-inject < test/corrected
-.. code:: bash
+3. Connect to the controller and query the monitoring services. Make sure the overcloudrc.v3
+ file has been copied to the controller (from the undercloud VM or from the Jump Host) in order
+ to be able to authenticate for OpenStack services.
- $ source openrc
- $ ceilometer sample-list -m interface.if_packets
- $ ceilometer sample-list -m hugepages.vmpage_number
- $ ceilometer sample-list -m ovs_events.gauge
- $ ceilometer sample-list -m mcelog.errors
+ .. code:: bash
-As you run each command above, you should see output similar to the examples below:
+ $ opnfv-util overcloud controller0
+ $ su
+ $ source overcloudrc.v3
+ $ gnocchi metric list
+ $ aodh alarm list
